Hi all,

I am running ETK (2019_10) on a home built cluster consisting of two nodes (8 cores, 16 threads, 64GB 4.3 GHz each).  I just finished my second node and am trying to run a simulation (BBHMedRes) over both nodes. For starters I am just running one process (one thread per process) on each node.  When I execute my simfactory submit command, I get one process with one thread on the node I submitted the simulation on.  However, I get one process with 16 threads on the second node which I don't want.  When I run on just the first node, the number of processes and threads per process I get are just what I specify in the simfactory submit command.  If I submit the simulation on the second node and just run on the second node I get processs/threads just what I specify in the simfactory submit command.  Its only when I run on multiply nodes that don't get the # of processes/threads that I specify.  Is there something I am doing wrong? I am using OpenMPI.

Thanks for any help, Tony...

Relevant data is:

1. RunScript:
   
   #!/bin/sh
   
   
   
   # This runscript is used internally by simfactory as a template during the
   
   # sim setup and sim setup-silent commands
   
   # Edit at your own risk
   
   
   
   echo "Preparing:"
   
   set -x                          # Output commands
   
   set -e                          # Abort on errors
